Abstract
An improved multi-part die assembly for forming a closed clip comprises a mounting structure, punch means, first and second gate-die members and simultaneous driving means. The punch means reciprocates toward and away from a clip-forming station on the mounting structure, and the gate-die members pivot toward and away from the clip-forming station. A crown die is defined on the punch means for cooperation with the crown of an open clip. First and second leg dies on the first and second gate-die members cooperate with the legs of the open clip. The simultaneous driving means drives the punch means and the first and second gate-die members simultaneously whereby the closed clip is formed by cooperation with the crown die and the leg dies.

An improved multi-part die assembly for forming an open clip having a crown and two spaced legs into a closed clip comprising:
- a mounting structure having a clip-forming station located thereon;
- punch means mounted on said mounting structure for reciprocating movement toward and away from said clip-forming station, said punch means and said mounting structure cooperatively defining means for guiding said reciprocating movement, said punch means defining a crown die for cooperation with said crown;
- a first gate-die member and a second gate-die member pivotally mounted on said mounting structure on opposite sides of said clip-forming station for pivotal movement toward and away from said clip-forming station, said first gate-die member defining a first leg die for cooperation with one of said two spaced legs and said second gate-die member defining a second leg die for cooperation with the other of said two spaced legs;
- and
- means for simultaneously driving the first and second gate-die members and the punch means toward said clip-forming station, said first leg die overlapping said second leg die when said gate-die members are both pivoted toward the clip forming station;
- whereby an open clip positioned at said clip-forming station is formed by cooperation of said crown die and said first and second leg dies with said open clip into a closed clip having overlapping legs.
